When using an electric fuel pump you should also add a secondary "AUTOMATC" power cut off.
Rangers, and most vehicles, with electric pumps have an Inertia switch, which is a metal weight that holds fuel pump's 12volt wires closed, in the event of a sudden stop(accident) or roll-over this weight should move, because of its "inertia" cutting power to fuel pump.
And this is a very good safety measure, but.............we are talking about your life here, and lives of any one else in the vehicle
Rangers will already have a Fuel pump relay in the engine bay, and it is operated by the computer Grounding this Relay's Coil to close it and send power thru the inertia switch and then to the pump.
Back when electric fuel pumps were starting to be used and Carbs were still being used auto makers came up with the Oil Pressure switch, this switch closes when oil pressure is above 5psi, and it is a GROUND switch
Engine provides the Ground via the threads on pressure switch, the one wire connection on the switch becomes a Ground when oil pressure is above 5psi.
If you connected one of these to the Fuel Pump relay's coil ground then fuel pump relay would only close/send power to fuel pump when engine was running.
So if there was a broken fuel line engine would stall and electric pump would stop pumping gasoline.
Carbs have reserve fuel in the bowl for startup, so don't need the fuel pump to come on instantly.
With fuel injection the fuel pump only runs for a few seconds with key on, then computer waits for RPMs to get above 400 before it sends power to fuel pump full time, and if engine should ever stall, computer would unGround the relay and cut power to electric pump.
So same setup as oil pressure switch, cheap and easy since you have all the parts now, just need to run 1 wire
1989 and up Ranger engines used oil pressure switches, not senders
